• Unable to connect to target iSCSI for ESX 3.5

  Hi all

  I have an esx 3.5 build 82663 (update 1). We took over this company, so we are migrating this data center. I understand tha patch isn't 5 update but it wasn't our environment and we try to turn it on.

  We have three esx servers

  (1) console production svc - 192.168.7.x

  (2) storage network - 192.168.9.x

  EqualLogic 3)-192.168.9.x

  (4) storage Switch - CISCO 3750 Switch

  (5) frames enabled on vswitch, vmknic, physical, switch, network interface cards, table vlan and storage.

  (6) software iscsi client allowed an outgoing connection through 3260 (tcp)

  Performed troubleshooting

  esxcfg-vmknic - l - seems ok and with activated jumbo frames

  esxcfg-NICS - l - looks ok with activated jumbo frames

  esxcfg-vswitch - l - looks ok with activated jumbo frames

  esxcfg-road - l - (looks good)

  192.168.7.0 255.255.255.0 local subnet

  192.168.9.0 255.255.255.0 local subnet

  by default 0.0.0.0 192.168.7.1

  Works of vmkping between the storage network interfaces (192.168.7.x) i.e. physical switch, equallogic, and other interfaces for esx storage network.

  vmkping s 9000 192.168.9.11 (equallogic san) works without packet loss.

  Ping does not work between interfaces.

  Ping of physical switch to the san and esx equallogic storage network interfaces work

  Access to LUNS equallogic shared among interfaces are restrticted by the ip address of storage network (192.168.9.x). The LUNS they check marks against them to have several initiators communicate with them.

  No enabled chap authentication anywhere.

  I had another server with the same configuration connection to it without problems to the only difference is esxi can be accessed and the esx servers cannot access.

  Our environment has been only esxi. This is the first time I use esx and a system of update 1 for iSCSI.

  I'm on the critical path to complete the project.

  It would be useful that I can get all the help you can.

  See you soon,.

  Knockaert

  If I'm not mistaken in your service console needed to have access to the storage network 3.5 too.  Try to configure a second service on the storage network console and see if you can view the LUNS.   Can also be useful to filter through the vmkernel logs and see if you notice any errors.

• solution for ESX iSCSI SAN

  Hello.

  We are looking into getting a SAN iSCSI for ESX.

  On readers, y at - there a big difference between sata and sas and sas 10K vs 15K?

  How iSCSI performance are compared to the SAN fiber?

  Can you guys recommend an iSCSI solution right?

  Excerpt from Dell PS4000 and it seems to be a good product.

  (On players, is there a big difference between sata and sas and sas 10K vs 15K?)

  Yes, 15 k SAS are faster and a bit more expensive, but worth it!

  (How iSCSI performance are compared to the fiber SAN?)

  ISCSI SAN is not as fast as the fiber, but compared to the local drive is a big improvement for your applications, users, etc.

  (You guys can recommend a good iSCSI solution?)

  Personally, I think Dell equallogic are great! PS600XV is what I put in place.

• How better to configure ports of ether-channel for use with iSCSI?

  I had a quick glance and find a number of different discussions about the best solution for simlar scenarios but nothing quite close enough to convince me to implement the proposed solution.

  The configuration that I was left with is not ideal, because it is not redundent. So I need to find a quick solution pritty.

  Two cards (each NIC goes to different switch) - Console of Service

  Two network cards (both in the same key) - vMotion

  Two network cards (they both go to the same switch) - Prod (10 discussions)

  Two network cards (they both go to the same switch in an ether channel) - storage (iSCSI)

  The environment is a cluster of three ESXi 4.1 ENT U1 + environment, connected to a vCenter STD.

  Here's what I intend to allocate, but hoped a nice person enough to suggest the best configuration. I realize the number of connections to Prod is excessive and we will reach neaver as bandwidth, but I have free network cards.

  Two cards (each NIC goes to different switch) - Console of Service

  Two cards (each NIC goes to different switch) - vMotion

  Four NICs (two pairs in different switches) - Prod (10 discussions)

  Four (#) - storage (iSCSI) network interface cards

  The part that concerns me is get the configuration for storage network cards just like we use the ether-channel, which seems to complicate things from what I've read.

  So in summary I want to use four NICs for storage and bandwidth is not wasted I currenlty have using the channel of the ether. If I can work it another way without the use of ether-channel I am pleased to see again.

  If I have not provided enough information to evaluate, please let me know and I'll give you more.

  Thanks in advance for any helpful information.

  So in summary I want to use four NICs for storage and bandwidth is not wasted I currenlty have using the channel of the ether. If I can work it another way without the use of ether-channel I am pleased to see again.

  First of all, let me squash the myth an EtherChannel gives you additional bandwidth for iSCSI. Each iSCSI initiator can use an uplink to an iSCSI target vSphere being limited to a hash value "IP". Given that the source and destination IPs are always the same, the hash is always the same.

  I wrote about it here in my post seriously, Stop "Using Port channels for vSphere storage traffic":

  http://wahlnetwork.com/2013/03/05/stop-using-port-channels-to-vSphere-hosts/

  I recommend to use the vmkernel ports link. It is available in 4.1, but not through the GUI.

• Implementation of electronic networks for ESX 3.5 with iSCSI?

  Well, I'll have a bit of a problem here...

  I have 3 VLAN:

  ID

  1 - network management

  2 - iSCSI network

  3 - production or Guest OS Communication LAN

  I can't figure out how to get properly configured ESX or something because my iSCSI storage is not being discovered. Can someone guide me on how my network cards should be configured? I have 6 network adapters and possibly their sticks, but for now I wanted to 1 for ESX management, 1 for iSCSI and 1 for the virtual computer network if that makes sense. If there is a better please let me know, but I defnitely want to configure my iSCSI is own VLAN (2). I have been through a few docs and can't make it work... Thank you...

  Initially, I had only a single device defined within the iqn.2012 - 10 .cpd .net: san.target01 and I was able to create a data store on the ESXi hosts that I have running in my lab. I then added a second disk (LUN 1 above), but I still show that the possibility of having the original data store. When I look at the "storage adapters" on another host, details the software iSCSI card show 1 target connected, 2 devices and 2-way. If I should not be able to mount MON 1 as a second data within the host store?

  I don't use iSCSI anywhere in production and only play with it so that I can familiarize myself with the portion of iSCSI for test VCP5-VTC. Any help would be greatly appreciated. Thank you.

  Has proved to be a problem with tgtd. I actually had to reboot the server to get exports to work properly - the normal command "tgtd restart service" has been leaving some kind of autour artifacts that prevented VMware to see the changes properly.

• iSCSI for Dummies (or at least for a UNIX / NFS guy)?

  I currently use a NFS for my data stores in a small lab environment, with 6 ESX host and a few Linux servers all share the same NFS mounting.  Now I'm looking in the deployment of iSCSI data store, and I was a little confused by some of the questions and warnings, I've seen in the posts here.

  Can anyone recommend a good resource for the rise on iSCSI, specifically with respect to its use with ESX and limitations to know her and the architect for?

  Such as:

  -Attach multiple ESX hosts and Linux servers to export even iSCSI (MON.)

  -Best practices for the Organization of virtual machines for iSCSI actions.

  -Implications of the "LUN."  As I understand it, a logical unit number is a logical SCSI disk.  Are there limits to the VMs per LUN or iSCSI clients attached to the LUN?

  Be aware that insofar as manual VMware, these two cover iSCSI Details:

  http://www.VMware.com/PDF/vi3_35/esx_3/r35u2/vi3_35_25_u2_3_server_config.PDF

  http://www.VMware.com/PDF/vi3_35/esx_3/r35u2/vi3_35_25_u2_iscsi_san_cfg.PDF

  Use iSCSI features can often require that you understand more you could for other types of storage:

  http://www.VMware.com/files/PDF/vmfs_resig.PDF

  My own tendencies:

  Create LUNS of 500 GB - this is based on VMware recommendation to limit LUN approximately 20 mV

  Store boot and small partitions in the VMFS data store.  For larger partitions, you can use initiator iSCSI to take better advantage of the advanced features of SAN.  I think it's certainly useful for virtual machines Windows on good iSCSI SAN, but don't know how it applies to Linux virtual machines.

  With respect to all data warehouses, you can have instant VM on try to keep about 20% free space.  Also consider the size of the swap files on the warehouses of data - by default they will be created the same size as the memory of the configured virtual machines when the virtual machine is running.

• How to configure rdm to use iscsi lun in a virtual machine using ms iscsi initiator?

  I have equallogic SAN attached to a cisco 3750

  switch. It comes to our storage network.

  Within the virtual machine for all readers of data other than my c:\ that has the operating system I would use iscsi data switch that has 4 network ports on four different nic cards already assigned.

  According to what I read a virtual machine can use only 4 nic so I have a Production network the other three that I would

  Use it for iSCSI data.

  Three ports of each virtual computer network for using ms iscsi with MPIO

  initiator.

  I have already attached the RDM using esxi 3.5 as a physical mapping of RDM.

  My question is how to configure the ports of the network adapter in the virtual machine?

  The VM network is on 172.19.2. * where iscsi is on 172.19.21. *.

  What would be the entrance on the network adapters in the virtual machine that is running ms win 2 k 3 r2 x 64.

• External template function (control and Simulation Module) on Linux using target

  Hello

  I am trying to run the 'EMI_Integrator.vi' for example on one OR cRIO-9024 (nor a myRIO).

  I moved the file 'EMI_Integrator.so' to the ' / or-rt/system ' on the cRIO and the .so file added to the target in the LabVIEW project. I can not navigate to the .so file directly so I specified the .so path manually, but the VI is not able to run and an error of-2366 'reissue model '.

  "You can find the original version of VI in the Finder for example OR", but I've included my modified version that has a LabVIEW project and targets already loading.

  Thank you

  Mitch

  Hello Mitch,

  If you want to use the external model on a 9024 node, you must copy the appropriate VxWorks library (.out) file to the/or-rt/system folder of the target. The .out file is located in LabVIEW\Examples\Control and Simulation\Simulation\External model Interface\EMI_Integrator\RT-Lib\vxworks.

  In LabVIEW, have the external model node refer to the file of the library appropriate for your operating system. In my case, I use a .dll for Windows file located in the folder EMI_Integrator, above.

  When I run the VI on the cRIO target, referring to the library on my host computer, it will automatically search the folder to/or-rt/system for a file with the same name with .out.

  Kind regards

• FQDNs for ESX environment when DNS servers are VMS within the ESX environment

  Hello

  I was wondering,

  When the implementation of a new infrastructure from scratch, with an ESX cluster from scratch

  and when the servers DNS themselves will run inside the cluster,

  Then, it is advisable to use IP addresses instead of the domain name COMPLETE for the right ESX environment?

  Here's what I've done so far:

  -installed 1 ESX host

  -installed donain controller as VM

  -installed PSC and VCSA

  -created the new cluster

  -installed the second ESX host, added to the cluster.

  I installed a VM DC as the first thing after the installation of the initial ESX host, I could have started using the domain name COMPLETE for the ESX environment at this time.

  However, I didn't do it.

  For installation of the VCSA and when you add ESX hosts to the cluster, I used IP addresses instead of the FQDN names.

  It seems stupid and dangerous for me to use domain COMPLETE the ESX hosts themselves, because the domain controller is running in the cluster.

  So I used IP addresses only to ensure the ESX HA cluster and the characteristics of heartbeat stay ok if something were to happen to the DNS server.

  However, the VCSA installation and when you add hosts to the cluster,.

  the MISTLETOE gave me a warning, indicating that it is preferable to provide a FULL domain instead of an IP address name.

  I am of the opinion that if you have no physical DNS servers, it is not a good idea.

  My opinion is that when your nameservers inside the ESX cluster itself and you do not have 2 redundant external DNS servers, so it is not wise to use the FQDN for your ESX hosts, PSC and VCSA setup.

  In my view, using the property intellectual property is much safer in this case.

  I was wondering what is your angle on it.

  Do you see the same way, or have different opinions?

  Hi smetter,.

  It is advisable to have a working DNS for vSphere environment however the use of DNS for things like vSphere HA have been removed in more recent versions of the product. Refer to the section of the guidelines of the general network of this document for more details: https://www.vmware.com/files/pdf/techpaper/vmw-vsphere-high-availability.pdf

  With this in mind I wouldn't be worried about use of FULL domain for the addition of services like the ESX host, etc.. Failure where HA would be restarting the virtual computer, there is no dependency on DNS so it will continue to work as expected and, subject to the availability of resources the virtual machine starts on another host.

  According to your vSphere licenses, you may also like to consider the implementation of anti-affinity DRS VM to keep your DNS Appart servers and on different hosts. This can prevent your servers DNS are declining when the failure of a host. You must have Enterprise edition or later for this.

  Kind regards.

  You reset the content of the table $Results on each iteration of the baseline.

  Try like this

• Electrodes for ESX 3.0.3

  I searched on the Site now for some time and was not able to find a list of the fixes available for ESX 3.0.3 I wonder to assess a couple of old ESX servers, they're all running 3.0.3 and esxupdate query that's all I get:

  [root@xxxxxx]#-l esxupdate query
  Installed software bundles:
  -Summary of name - Date installation-
  3.0.1 - 32039 22:03:16 08/25/09 3.0.1 full version of VMware ESX Server
  3.0.3 - 104629 22:15:12 08/25/09 3.0.3 full version of VMware ESX Server
  For the differential RPM list, use the - l /-listrpms option.

  I guess that there were patches since 3.0.3 - 104629, I believe that the Client has never implemented any, also, there are no deposits configured on these servers.

  Y at - it a list to see which patches if released after 3.0.3 - 104629?

  A big thanks to the guys of advnace

  See you soon
